A member made of cold-worked columbium is 15 inches long and has a rectangular cross-section 1/4 in by 3/4 in. This member is under a tensile load of 5,000 lb.
Modulus of elasticity, E = 22.7 x 106 poisson's ratio μ = 0.28.
Assuming elastic behavior, determine:
(a) total change in Length
(b) lateral strain
(c) total change in Volume
